http://zeiss-campus.magnet.fsu.edu/articles/lightsources/mercuryarc.html WebFluorescence is luminescence caused by electromagnetic radiation. Visible light can cause luminescence; shine a pure violet light at a ruby, and it will glow red, as it has absorbed the violet light energy and used it to create red light. But light-induced luminescence is uncommon and hard to see.
